oss panic on OpenSolaris 0508

Postby JasonMars » Mon Jul 07, 2008 9:10 am

My machine is running opensolaris 0508 and the sound card is Intel ICH.
My system panic several times due to oss driver, I run the mdb to check it and found it panic on oss_audio_sync when it tried to report message to FMA after it got timeout from oss_sleep. During that, it panic becase of NULL deference.

The panic always happens on the cpu schedule some apps like "firefox or thunderbird". You can see from the following analysis.

Here is the detail steps:
1. running mplayer and it play well.
2. OS panic accidentally.

Did I report the bug in the correct location? Please tell me if I report in the wrong place.

Are there any bug-track system I can report the bug to. Maybe it is an existing bug.
